10 April 2008 – Tango Meeting – A.Buteau ICALEPS 2005 Successes Standardisation at the Dservers is a success Many Dservers shared between Machine and BL or between Bls About 250 Dservers are in production Standardisation of application is in many cases a real success For example SALSA is used on 90% of the Beamlines And by the way NeXus file format is now a de facto standard for data file format at SOLEIL Idem for MAMBO, BENSIKIN, etc..
